BOBBIN-GLEANING ATTACHMENT FOR FILLING-REPLENISHING Looms.

Application filed April 12, 1927. Serial No. 183,038.

This inventionrelates to filling replenishing looms and is more particularly directed to bobbin cleaning attachments associated with such looms for cleaning the ejected fill- 6 ing carriers or bobbins of waste yarn or thread during the 100111 operation.

In that type offilling replenishin looms wherein replenishment is effected y the change of filling carriers or bobbins in the H shuttle, the ejected filling carrier contains a quantity of yarn which is left on the bobbin to insure a full pick of filling in the shed on the last flight of the shuttle preceding filling replenishment. Before such bobbins can be rewound with filling it is necessary that the waste filling thereon shall be removed, and it has heretofore been proposed toprovide means for this purpose in filling replenishing looms, so that during the inter val between filling replenishments the waste yarn maybe withdrawn from the ejected filling carrier.

Where the bobbin cleaning element consists of a rotary member against which the filling carrier rests during the cleaning operation, the filling carrier has heretofore been supported in such position by a hinged bottom or flap which on replenishment of filling is moved for the discharge of the cleaned filling carrier or bobbin. It happens at times that the ejected filling carrier will be thrown into bobbin cleaning position before the 'hingedbottom or movable flap has returned to its bobbin supporting position, with the result that the bobbin still containing waste yarn will be dischargedwithout being cleaned.

An important feature of the present invention therefore consists in providing a 4 bobbin cleaning attachment for filling replenishing looms, wherein means are pro' vided for catching and supporting the incoming filling carrier away from bobbin cleaning positlon until after the cleaned bobbin has been discharged and thereupon permittin such incoming filling carrier to move to bob in cleaning position after the lower movable wall or support has reached a position to prevent the discharge of such uncleaned filling carrier.

More specifically stated, the present invention providesai bobbin receiver having a bobbin cleaner against which the bobbin to be cleaned rests during the bobbin cleaning operation, andassociated therewith is a shaft 5 on which is mounted the transferrer lower wall or flap which supports the bob-' bin in cleaning position, and to prevent the incoming bobbin from moving directly to bobbin cleaning position untll after the lower wall or flap has been closed or partially closed, the present invention includes a bobbin catcher normally supported to 1'0- vide a passageway for the incoming filing carrier towards cleaning position, said catcher being moved on replenishment of filling to catch and support the incoming filling carrier and then to release it for movement to bobbin cleaning position.

The invention and new combination of parts and novel features thereof will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. 1 is a perspective view of arts of a filling replenishing loom having t e present invention associated therewith;

Fig. 2 is a vertical section throu h the bobbin receiver and associated parts, t e latter being shown in their normal position during the bobbin cleaning operation; and

Fig. 3 is a similar section showing the relation of parts during replenishment of filling with the bobbin catcher closing the passageway for the incoming filling carrier towards bobbin. cleaning position.

. The loom frame 1 may be of usual construction and, as shown, the breast beam 2 has mounted thereon the hopper or magazine stand or support 3, the rotary member of the magazine, which may be of usual type, being supplied with filling carriers 4 containing a supply of filling.

Mounted upon the support 3 is the stud 6 having a dog 7 which is engaged by a hunter on the lay when filling replenishment is to be effected. These parts may be of usual construction and need no further explanationsince they are now well understood in the art.

Secured to the loom frame is a bracket 8 on which is mounted a support 9 for a bobbin receiver 10, the bottom of said receiver being shown as open, as at 11, so that cleaned 1 bobbins may pass therethrough to a bobbin can 12 beneath.

The bobbin receiver 10 is provided with a shaft 13 which, as shown, extends transversely of the receiver, and has mounted bobbin cleaning position.

thereon the rotary bobbin cleaner 14 which is preferably provided with a roughened surface, such, for instance, as teeth 15, for engagement with thewaste yarn upon the bobbin to be cleaned, and by which such waste yarn is removed from the bobbin. One end of the shaft 13 extends beyond the bobbin receiver 10, asindicated in Fig. 1, and is provided with a pulley Hover which passes a belt 18, connected with some going part of the loom, to cause rotary movement of the shaft13 and the bobbin cleaner1 l mountedbobbin catcher 26 are secured.

thereon while the loom is in operation.

In the present instance of the invention, the belt 18 is actuated from. a belt pulley 19 on the cam shaft 20 and, as indicated in Fig.1, thepulley 19 may be coi'ivenient-ly formed on the hub portion of the pick cam 21, the construction being such that the rotary movement of the cam shaft 20 causes rotary movement of the bobbin cleaner.

Pivotally mounted on the bobbin receiver 10 is the lower wall or flap 22 which is ad jacent to the bobbin cleaner, and, as indicated in Fig. 2, serves as a support for the bobbin being cleaned, the yarn of which is engaged by the rotary bobbin cleaner and withdrawn from the bobbin. As indicated in the drawings, the bottom wallor flap 22 is secured. to a shaft 23 which may be con veniently supported by the bobbin receiver 10.

Secured to the outwardly extending-end of the shaft 23 is an arm 24 through the medium of which the lower wallor flap 22- may be moved, as will presently appear, to cause the lower wall or flap to move away from the bobbin cleaner 14' in a downward direction to permitthe discharge oi. a cleaned bobbin, as indicated in Fig. 3.

Extending transversely of the bobbin receiver above the bobbin cleaner is the shaft 25 to which is secured the bobbin catcher 26, the lower end portion which, as at 27, is normally maintained in proximity to the bobbin cleaner 14, to provide a passageway .28 by which the bobbin on the bobbin cated in Fig.2. The bobbin catcher 26 may be formed either as sheet metal or of any other usual or well-known material, andis normally inclined, as indicated in Fig. 2, so that the bobbin to be cleaned and resting thereon, as indicated inFig. 3, will, when the bobbin catcher is in normal position, be directed through the passageway 28 into If desired, and especially whenthe bobbin catcher is formed of metal, a stop 29 may be employed to ins sure that the bobbin catcher when. in normal position shall rest substantially in relation to the parts as indicated in Fig. As hereinbefore stated, the bobbin catcher 26 is secured to the shaft 25 passing transversely of the bobbin receiver, and on the outer end portion of the shaft 25 is an arm 30 of the same eneral character as the arm 24, but prefera 1y longer, as indicated in Figs. 2 and 3. The arms 24 and 30 are connected for concurrent movement by a link 31 pivoted at 32 to the arm 24 and at 33 to the arm 30, the construction being suchthat upon movement of either of the arms 24 or 30 concurrent movement will be imparted to the other arm andto the respective shafts 2 3 and 25 on which the lower wall 22 and the In accordance with the present invention, the lower wall 22 and the bobbin catcher 26 are normally positioned during weaving operation'as indicated in Figs 1 and 2, and movement thereof into the position indicated in Fig.3 and then back to normal position is eflected during replenishment of filling. Mounted on the loom frame is the transverse or change shaft 34 to which is secured an arm 35 connected at 36 to a link 37 which in the present instance is pivotally connected to the arm 30 at 38, the construction being such that on rocking movement of the transverse or change shaft 34, as usual in fillin replenishinglooms to actuate the replenishing mechanism, the bobbin wall or flap 22 and the bobbin catcher 26 will be first moved from the position indicated in Fig. 2 to that indicated in Fig. 3, wherein it will be noted that thebottom wall has been moved downwardly away from the bobbin cleaner, and the bobbin catcher 26 has been moved upwardly away from the bobbin cleaner to close the passageway 28, so, that an incoming filling carrier cannot directly move to bobbin cleaning position. Duringrocking movement of the transverse, or rock shaft 34 in the opposite direction, however, the lower wall 22 and the bobbin catcher 26 will be returned to their normal position, as indicated in 2. As hereinbefore noted, it is desirable thatthe incoming filling carrier a,-as indicated in Fig. 3, shall not be released for movement to its bobbin cleaning position until after the bottom wall or flap 22 has sufliciently moved to its initial position to provent the discharge of the incoming filling carrier, and therefore retain it in bobbin cleaning position, a condition which is con-1 trolled by the connections between thcshafts 23 and 25 and the actuating JIlfiClitDlSllT therefor. In other woods, whenthe parts are in position as indicated in Fig. 3,:1nd. the lower wall or flap 22 has been snfih ciently opened to permit the discharge of a. cleaned filling carrier or bobbin, the bobbin catcher 26 is in upward bobbin holding position, and on reverse movement of the door or flap 22 and the bobbin catcher 26, the lower wall or Hap 22 will berfirst moved sufii ciently towards the. bobbin cleaner to pre-,

ventdis charge of the bobbin (1 on the bobbin catcherwhen the latter moves towards the bobbin 'cleaner and opens the passa eway 28 for movement of the bobbin to be c eaned to cleaning position.

When filling replenishment is efiected, the ejected fillingucarrier with the waste yarn 1 thereon is thrown downwardly and frontwardly into the bobbin receiver, the parts then being in the position indicated in Fig.

" but, as shown in the present instance, it is formed of a strip of'canvas 39 which may be secured at 40 near the top of the bobbin receiver and at a point 41."v In the preferred construction, the lower end of the stop wall 89 is spaced from the front wall of the bobbin receiver by a spacer 42 interposedbetween thefront of the bobbin receiver and the lower end of the stop wall 39. In the present instance, the spacer 42 carries a rod 1 about which the end of the canvas forming the stop wall 39 may be looped, as indicated, although it is obvious that any appropriate means may be employed for this purpose.

The present invention, as will be noted from the construction and operation hereinbefore described, provides a bobbin cleaner in connection with which there is a bobbin catcher which is moved on replenishment of filling into bobbin catching position to close the passageway leading to the bobbin cleaning position and thereby prevent movement 01 the incoming filling carrier directly to cleaning position until after the bottom wall or flap 22 has been moved sufficiently towards its initial position to prevent the incoming filling carrier from being discharged. On replenishment of filling, both the bottom wall and the bobbin catcher are moved in opposite directions from the bobbin cleaner, and on the next or reverse movement of the transverse or rock shaft, these parts will again be returned to their initial position, the construction being such that the incoming filling carrier will not be released by the bobbin catcher until after the bottom wall or flap 22 is closed sufficiently.

towards the bobbin cleaner to prevent the incoming filling carrier which is to be cleaned from passing downwardly into the bobbin can.
